Fish are fish and all fish eat the same food. It's not true. Because farmed fish are not found in their natural habitats and therefore cannot eat the same food as wild fish, they need a certain amount nutrients depending on their species.
When designing fish feed, nutritionists must ensure there are at minimum 40 essential vitamins, minerals, and amino acids. They usually include fish oil, fishmeal and trimmings in their feed.
Fishmeal and fish oil are used in carnivorous fish feeds. This is used in fish feeds to keep fish healthy as it contains all the essential proteins they require. As fish consumption has increased, so has the cost of fish oil and fishmeal.
Nutritionists had to find suitable alternatives over the past few years. Since 1980s, the percentage of fish oil and fishmeal used has dropped from 70% to 30%. As the alternatives are more sustainable, most fish farms have reduced the amount of fishmeal or fish oil they use. www.floatingfeedmachine.com
